Claude

Hanzo MCP

Claude takes Hanzo's tools one way, Local: hanzo-mcp on your machine, started with npx -y hanzo mcp (needs Node.js). With no key set it uses the sign-in hanzo login stored, so there is no key to paste (MCP).

Claude takes a key only through request headers, which are a limited beta in its connector screen.

Claude Desktop: open Settings > Developer > Edit Config, then add to claude_desktop_config.json.

{
  "mcpServers": {
    "hanzo": {
      "command": "npx",
      "args": ["-y", "hanzo", "mcp"]
    }
  }
}

Claude Desktop reads claude_desktop_config.json from ~/Library/Application Support/Claude/ on macOS, %APPDATA%\Claude\ on Windows and ~/.config/Claude/ on Linux. An app started from the Dock or the Start menu does not read your shell's PATH: if it cannot find npx, write the full path which npx prints as the command.

claude.ai in the browser reaches remote servers only, from Anthropic's cloud, so the local server runs in Claude Desktop. Claude Code, in the terminal and the IDE extensions, is its own page.
